60 Minutes On This Bicycle Can Power Your Home For 24 Hours - Walden Labs

60 Minutes On This Bicycle Can Power Your Home For 24 Hours - Walden Labs


When an individual pedals the bike, the action drives a flywheel, which turns a generator and charges a battery. This means from just one hour of pedaling, a rural household can be supplied with energy for 24 hours.

Is recycling worth it in 2016

Recycling update 

“Five R’s” (instead of the usual three) in order : Refuse what they don’t need, reduce what they do need, reuse by avoiding disposables and buying secondhand, recycle what they can’t refuse, and rot (compost) what’s left. 

It is useful to see real green work based on provable facts . Diversions of the waste stream make economic and natural sense  and should continue to be nurtured.

Fast repurposed structures

Creative container uses
Cdn and pricey
Honomobo currently offers three models. The smallest, H01, is based on a single shipping container and has a total floorspace of 144 sq ft (13 sq m). Conceived as an additional bedroom that could be installed in the garden, it features a bedroom and bathroom. The cost comes in at US$38,801, plus taxes and shipping (but including installation).
Moving up in size, the H02 comprises two shipping containers joined together. The interior measures 352 sq ft (32.7 sq m), which is split between a lounge, kitchen area, bedroom and bathroom. This model fetches $78,646.
The firm's largest two models, the H03 and H04, measure 528 sq ft (50 sq m) and 640 sq ft (60 sq m), respectively, with the former costing $102,743 and the latter costing $120,136. This largest model includes two bedrooms, with a relatively generous kitchen/bathroom area and bathroom.

Skyrider One - Very First Flight of the Electric Scooter & Paraglider



Skyrider One is the first prototype of an electric scooter, which is also an electric paraglider. It is the easiest way, to have something like a flying car. You can drive to your airstrip, fly to somewhere, and drive home after landing. With all electric drive, it is quiet and does'nt make any pollution. It can be used in areas, where combustion engines are not allowed. And two wheels are enough, no need for more. Take off and landing is easy with some help of your feet.
Flying in thermals is possible and can increase the endurance up to several hours. Enjoy the beautyful landscapes of La Palma (Canary Islands).

Specs:
Hub motor: up to 6 kW
Prop motor: up to 13 kW
Prop diameter: 130 cm
System voltage: 52 V
Battery: 14S LiPo, 58 Ah, 3 kWh (one or two packs)
Recharge time: 3 hours
Weight: 108 kg
Endurance: 60 km on road, 15 min. in air (one battery) 120 km on road, 30 min. in air (two batteries)

Material that recycles sunlight could be next big leap for solar cells

Earlier this year, the US' National Renewable Energy Lab announced that a new record had been set for solar cells that were able to convert sunlight to electricity at the rate of 29.8 percent using a silicon-based cell. If the Cambridge research can be translated into a working solar cell, there's a good chance that record won't stand for long. Plus, with a recent advance that makes perovskite cells cheaper and more durable, silicon's days in the sun might soon be drawing to a close.

Material break through for solar?

tomatoes waste to electricity

constructive waste diversion ? tomatoes
A team of scientists is exploring an unusual source of electricity — damaged tomatoes that are unsuitable for sale at the grocery store. Their pilot project involves a biological-based fuel cell that uses tomato waste left over from harvests in Florida. We acknowledge primary contributions from Alex Fogg, Daniel Franco, Joe Wilder, and Dr. Komisar.

Rand aims to make electric boating a Picnic

Rand aims to make electric boating a Picnic the key is electric the problem is the added weight of the batteries

"Owners have a choice of either lithium or gel batteries that can be charged while plugged in at the dock, removed and charged elsewhere, or charged through the boat's solar cells. The available Torqeedo electric outboard motor can be easily removed to transport back and forth between the boats when necessary."

@mhpr262 An electric speed boat would still be pretty expensive and heavy. Speed boats consume a ton of fuel which would mean needing really high capacity batteries. A 24" ski boat boat uses a ~55 gal tank meaning you might need about a 400 kWh battery which itself would weigh close to 5,000 lbs (~2,000 kg).
