0:00:00.000,0:00:02.000
Je, mnaona mahali ambapo nimeketi?

0:00:02.001,0:00:07.000
Tunakuletea hili kwenye kipindi hiki cha [br]R&D Africa kwenye AAU TV.

0:00:07.001,0:00:12.000
Tunamwangazia kwa kijana Lawrence Adjei, [br]ambaye ameweza kutengeneza

0:00:12.001,0:00:16.260
pikipiki hii ya umeme kwa kutumia [br]betri za vipakatalishi vilivyoharibika.

0:00:16.260,0:00:17.890
Tegea.[br]Tutakuonyesha zaidi.

0:00:26.050,0:00:30.664
Katika enzi ambapo ulinzi wa mazingira, [br]siha na usafiri unaotunza mazingira

0:00:30.664,0:00:34.092
unathaminiwa na kufanywa kwa sana na watu,

0:00:34.402,0:00:37.000
kinachokujia akilini wakati [br]usafiri unaokuruhusu,

0:00:37.000,0:00:38.614
kuepuka msongamano wa trafiki,

0:00:39.614,0:00:42.000
usiochafua hewa na unaotunza mazingira unatajwa.

0:00:45.883,0:00:49.930
Baiskeli zinazotumia umeme [br]zina vifaa vya kielektroniki

0:00:49.930,0:00:52.509
vilivyowekwa kusaidia au kuchukua [br]nafasi ya kuendesha mwenyewe.

0:00:52.985,0:00:55.000
Zina manufaa kadhaa.

0:00:55.425,0:00:59.522
Hazitumii mafuta mengi, zina mwendo [br]wa kasi, hupunguza msongamano wa trafiki

0:00:59.522,0:01:01.850
na hazichafui mazingira.

0:01:04.020,0:01:07.439
Kwa sana wavumbuzi wanategemea [br]betri kama vile lithium-ion,

0:01:07.641,0:01:08.841
nickel-cadmium,

0:01:09.231,0:01:10.852
betri za lithium-cobalt

0:01:10.921,0:01:11.921
lead acid,

0:01:12.081,0:01:13.801
nickel-metal hydrate,

0:01:13.801,0:01:14.851
lithium-manganese

0:01:14.851,0:01:18.000
na betri za lithium-ion polymer[br]kama vifuasi.

0:01:18.845,0:01:22.068
Cha kushangaza, kijana mchanga wa Ghana,[br]Lawrence Adjei

0:01:22.068,0:01:26.030
amechagia kwenye uvumbuzi katika [br]sekta ya baiskeli za umeme.

0:01:26.030,0:01:29.075
Anatumia betri za vipakatalishi, ambazo ananunua

0:01:29.075,0:01:34.430
kutoka kwa maduka ya takataka kompyuta [br]huko Accra ili kutengeneza baiskeli zake.

0:01:34.800,0:01:38.182
Anajulikana kuwa raia wa kwanza wa [br]Ghana kutengeneza baiskeli za umeme

0:01:38.182,0:01:42.000
kutoka kwa betri za vipakatalishi[br]na amejifunza.

0:01:45.471,0:01:50.088
Naishi karibu na Lawrence na [br]mimi ni msaidizi wake.

0:01:50.088,0:01:52.222
Hii si mara yangu ya kwanza kuendesha.

0:01:52.472,0:01:54.460
Nimekuwa nikiendesha pikipiki kwa miaka miwili sasa.

0:01:54.460,0:01:56.463
Hali ya uendeshaji ni tofauti.

0:01:56.621,0:02:00.202
Tofauti. Siwezi hata kulinganisha kwa [br]sababu kuendesha baiskeli ya kawaida...

0:02:00.202,0:02:01.370
kuna uchungu mwingi.

0:02:01.370,0:02:05.740
Na kisha unaweza kupenda idadi [br]ya kilomita unazohitaji kwenda.

0:02:06.001,0:02:10.339
Kwa hivyo hii ni tofauti kabisa [br]ikilinganishwa na nilizowahi kutumia.

0:02:10.339,0:02:13.700
Hii ina gia tatu [br]na hizo nyingine hazina.

0:02:14.280,0:02:20.543
Ina breki ambayo inachaji betri wakati [br]unaitumia, baiskeli nyingine hazina.

0:02:21.001,0:02:24.537
Ina lango la USB ambalo linaweza [br]kuchaji simu yako

0:02:24.537,0:02:26.250
au kutumia mwangaza wa USB.

0:02:26.541,0:02:28.254
Vitu ambavyo havipo kwa nyingine.

0:02:28.811,0:02:32.062
Na pia ina kengele, nyingine [br]hazikuwa na kengele.

0:02:32.962,0:02:36.634
Na kisha unaweza kusimama [br]mara moja ukitumia breko.

0:02:36.794,0:02:38.010
Zinasimama mara moja.

0:02:38.370,0:02:40.525
Inayofuata. Tukiangazia betri,

0:02:40.525,0:02:42.944
ina kiwango cha juu unachoweza kutumia,

0:02:43.204,0:02:45.586
kuweka mwanga kwa nyumba.

0:02:49.275,0:02:52.640
Hapa ndipo Bw Lawrence AJ [br]hufanya uvumbuzi wote.

0:02:52.640,0:02:55.647
Hapa ndipo utengenezaji [br]wa baiskeli za umeme

0:02:55.647,0:02:58.920
kutokana na betri za vipakatalishi[br]vilivyoharibika hufanyika na

0:02:58.920,0:03:01.000
Kwa sasa nipo hapa na Bw Lawrence.

0:03:01.601,0:03:03.656
Tuonyeshe [br]mchakato unaohusika katika

0:03:03.656,0:03:07.000
matumizi ya betri hizi ili [br]kutengeneza baiskeli ya umeme.

0:03:07.481,0:03:09.640
Kwa hivyo kuna betri hapa.

0:03:09.993,0:03:11.986
Kwa hivyo, unazipasua hivi.

0:03:12.511,0:03:15.121
Wakati mwingine unakunja au...

0:03:15.891,0:03:16.891
unatumia koleo.

0:03:17.247,0:03:18.267
Sawa

0:03:21.533,0:03:24.500
Unaona kuwa hatutumii seli zote.

0:03:24.551,0:03:26.054
Hii iko hapa, imechomoza.

0:03:26.784,0:03:28.870
-Sawa[br]-Huwezi kutumia hii, kwa hivyo

0:03:28.870,0:03:30.063
Unatafuta tofauti.

0:03:30.654,0:03:31.753
Jaribu nyingine.

0:03:38.610,0:03:39.639
Inayofanana.

0:03:39.639,0:03:42.665
Hii iko sawa. Kwa hivyo unachukua [br]mathabodi

0:03:42.665,0:03:44.180
- ya betri. Kwa hivyo...[br]- Sawa

0:03:44.439,0:03:45.439
Kwa hivyo kuziondoa

0:03:46.058,0:03:48.828
[Haisikiki]

0:03:54.638,0:03:56.965
Kisha ondoa seli zake hivi.

0:03:57.463,0:03:58.503
Sawa

0:04:00.391,0:04:02.780
Kwa hivyo kwa jumla, [br]unahitaji seli hizi ngapi?

0:04:03.001,0:04:04.260
Nahitaji nyingi, lakini

0:04:04.260,0:04:05.991
Nina betri 6 pekee hapa.

0:04:05.991,0:04:07.001
Sawa

0:04:07.001,0:04:12.000
Kisha unapima kwa kutumia votimita ili [br]uone iwapo kuna kiwango cha volti ndani.

0:04:12.001,0:04:15.000
Unahitaji wastani wa [br]volti ngapi katika betri?

0:04:15.001,0:04:17.588
Nafikiri kama volti 2.5.[br]Volti 2.5 ni sawa.

0:04:17.588,0:04:19.131
- Sawa[br]- Hii ni nzuri

0:04:19.131,0:04:20.968
- Sawa[br]- Kisha tunakuja hapa

0:04:20.968,0:04:22.840
na kupima kupitia mashine hii hapa.

0:04:22.840,0:04:24.759
Hii inaitwa Opus.

0:04:24.759,0:04:27.096
Hii hufanya vipimo vya kiwango.

0:04:27.096,0:04:30.000
- Sawa[br]- Kwa hivyo unaweka seli ndani hivi.

0:04:30.001,0:04:32.425
Unaweza kuona kuwa inachaji, kwa hivyo...

0:04:32.425,0:04:34.940
Itachaji betri kwa [br]takribani saa mbili

0:04:34.940,0:04:36.470
- Sawa[br]- Saa mbili pekee

0:04:36.470,0:04:43.000
Baada ya hilo, mashine itaondoa umeme[br]kwenye betri na kukuonyesha kiwango,

0:04:43.159,0:04:44.970
-Sawa[br]-Kisha tunaiondoa.

0:04:44.970,0:04:48.360
Kisha tunaandika kiwango juu yake.

0:04:52.001,0:04:53.951
Kulinganisha vitu vingine pia

0:04:53.951,0:04:58.000
Ina kifaa cha Bluetooth ndani yake, [br]unachoweza kutumia kusanidi simu yako.

0:04:58.270,0:05:02.309
Kwa hivyo fikiri naenda kwa kasi ya juu,[br]haupunguzi kasi

0:05:02.309,0:05:05.000
kwenye simu yako na [br]kisha itapungua kiotomatiki.

0:05:05.001,0:05:07.000
Haijalishi mchapuko.

0:05:07.001,0:05:10.000
Kwa baiskeli nyingine, [br]hazina gia ya nyuma.

0:05:10.001,0:05:12.000
Unahitaji tu kuzikuma nyuma hivi.

0:05:12.001,0:05:13.778
Lakini hii ina gia ya nyuma.

0:05:13.778,0:05:15.000
Kwa hivyo hamna haja.

0:05:15.001,0:05:19.000
Wakati umewasha ufunguo, bonyeza tu [br]kitufe na kisha unaanza kwenda.

0:05:19.001,0:05:21.919
Haichapuki kama unapokua [br]kwenye kasi ya juu

0:05:21.931,0:05:27.000
lakini ina nguvu na [br]inapunguza kasi taratibu.

0:05:27.250,0:05:31.000
Bila kujali kizuizi, [br]itapunguza kasi taratibu.

0:05:31.001,0:05:34.000
Nafikiri haya ni yote kuihusu.

0:05:34.001,0:05:37.000
Kwa baiskeli nyingine, [br]hatuna shokomzoba za mbele.

0:05:37.100,0:05:41.800
Na kisha, shokomzoba za mbele, [br]tukizungumzia hili, limejazwa hewa.

0:05:41.800,0:05:43.570
Ni tofauti na hilo lingine.

0:05:43.570,0:05:47.000
Hiyo nyingine ina hewa kidogo [br]na mafuta mengi.

0:05:47.001,0:05:51.000
Lakini hii ina hewa, kwa hivyo [br]unasimama mara moja.

0:05:51.001,0:05:53.000
Na unaona kuna ya nyuma pia.

0:05:53.001,0:05:55.000
Pia ni tofauti upande wa nyuma.

0:05:55.150,0:05:57.347
Kwa kweli, baiskeli nyingine, unapoendesha

0:05:57.347,0:06:00.721
na upitie kwenye shimo, [br]unahisi uchungu kwenye kiuno.

0:06:00.721,0:06:02.420
Lakini kwa hii, huhisi uchungu.

0:06:02.420,0:06:05.000
Unapitia tu shimoni na unakuwa sawa.

0:06:05.001,0:06:08.165
Kwa hivyo wakati wowote unapoendesha[br]baiskeli hii, inakufanya

0:06:08.177,0:06:11.000
utamani kwenda zaidi na zaidi.

0:06:11.150,0:06:14.700
Ni vyema zaidi kuwa na [br]mojawapo ya baiskeli hizi.

0:06:18.860,0:06:20.625
Jina langu ni AJ Lawarence.

0:06:20.650,0:06:23.000
Naishi Kaswa katika eneo la kati la Ghana.

0:06:23.075,0:06:25.934
Akiwa na miaka 11, wakati [br]Lawrence aligundua talanta yake,

0:06:25.946,0:06:31.000
alijifunza kucheza na vifaa vya [br]kielektroniki kama vile kompyuta.

0:06:31.425,0:06:34.170
Mwaka mmoja baada ya mvuto [br]wake kukua katika nyanya hiyo,

0:06:34.182,0:06:37.000
alichukua kasi ya [br]kurekebisha baiskeli.

0:06:37.001,0:06:40.000
Hadi leo, bado [br]anarekebisha baiskeli kadhaa.

0:06:40.100,0:06:44.000
Kufikia sasa, Lawrence ametengeneza na[br]kuuza baiskeli nne za umeme mwenyewe.

0:06:44.125,0:06:49.810
Baiskeli ya sasa ina vitu vilivyoboreshwa[br]ikilinganishwa na alizotengeneza zamani.

0:06:49.810,0:06:51.831
Profesa Jaya anatazamia [br]kuwasiliana na

0:06:51.831,0:06:54.220
vyuo kwa ajili [br]ya ushirikiano

0:06:54.250,0:06:59.000
ili kuboresha mawazo [br]yake ya ubunifu.

0:06:59.001,0:07:04.000
Ana ndoto ya kutumia sola kuendesha [br]baiskeli zake baadaye, lakini anahitaji

0:07:04.001,0:07:06.927
ushirikiano na vyumo na taasisi za

0:07:06.939,0:07:10.000
kiufundi ili kuboresha [br]utengenzaji kutoka sampuli

0:07:10.450,0:07:12.000
hadi kuwa biashara.

0:07:12.150,0:07:15.005
Katika ushirikiano huo, [br]anatafuta kuwafunza

0:07:15.017,0:07:18.000
wanafunzi wa kiufundi kuboresha[br]ufahamu wao kuhusu elektroniki.

0:07:21.900,0:07:23.761
